3 Claims, 6 Drawing Figures PATENTEU FEB 4I975 SHEEI 10F 2 SHEET 2 OF 2 mli illii PATENTED F55 4|9?5 1 BELLOWS SMOKING PIPE SUMMARY OF THE INVENTION of This invention relates to a smoking pipe device which is provided with a bellows body member which defines an enlarged smoke expansion cooling chamber that can be selectively expanded and contracted so as to receive smoke from a smoke generating bowl at a relatively high temperature and to deliver it to the smoker at a relatively lower temperature.

The resilient, partially collapsible bellows body member defines an enlarged smoke expansion cooling chamber therein. The bellows body member is provided with an externally mounted smoke generating bowl which is in open communication with the smoke expansion cooling chamber through smoke inlet check valve means selectively positioned intermediate the bowl and the smoke expansion cooling chamber.

The bellows body member is also provided with an externally mounted tubular stem mouth member which is in open communication with the smoke expansion cooling chamber through smoke outlet check valve means positioned intermediate the smoke expansion cooling chamber and the tubular stem mouth member.

After an initial partial collapsing, compression or contraction of the bellows body member by the user, the bellows body member is expanded so as to draw smoke from the smoke generating bowl through the smoke inlet one-way check valve into the expanding smoke expansion cooling chamber. Thereafter, the user can seletively compress the bellows body member so as to drive the cooled smoke from the smoke expansion cooling chamber through the smoke outlet oneway check valve into the tubular stem mouth member for selective delivery to the mouth of the user.

Thus, the present invention consists of a bellows smoking pipe device which has a smoke expansion cooling chamber that can be selectively expanded and contracted so as to vary the volume thereof. As the smoke expansion cooling chamber is expanded to its full maximum volume, the hot smoke which is drawn thereinto is expanded and is thus cooled in accordance with well known gas law principles. Thereafter, as the bellows body member is compressed or contracted, the smoke expansing cooling chamber is correspondingly decreased in volume and the cooled smoke is expelled therefrom through the smoke outlet one-way check valve into the tubular stem mouth member in association therewith.

It is therefore an object of this invention to provide bellows smoking pipe having a selectively variable smoke expansion cooling chamber whereby cooled smoke is delivered to the user.

Another object of this invention is to provide a bellows smoking pipe which cools smoke received from a smoke generating bowl in association therewith without the need for ancillary coil and/or water cooling means.

Another object of this invention is to provide a smoking device consisting of a bellows body member which defines a smoke expansion body member therein.

Still another object of this invention is to provide a bellows smoking pipe which receives smoke through a smoke inlet valve into a smoke expansion cooling chamber during expansion thereof and delivers cooled smoke through a smoke outlet valve from the smoke expansion cooling chamber during compression thereof.

Other objects and advantages found in the construction of the invention will be apparent from a consideration of the following specification in connection with the appended claims and the accompanying drawings.

SPECIFIC DESCRIPTION As shown in FIG. I, the bellows smoking pipe I1 is provided with a bellows body member 12 having a smoke generating bowl I3 and tubular stern mouth member 14 externally mounted thereon.

ln its preferred configuration, the bellows body member 12 has a generally hollow cylindrical configuration with flat end portions 15 and 16. This is shown generally in the drawings and more specifically in the crosssectional view of FIG. 5. The bellows body member 12 is fabricated from a resilient plastic material and is partially collapsible due both to the resilient material from which it is constructed and the overall bellows-type configuration thereof. While the preferred embodiment of the bellows body member 12 has a substantially cylindrical configuration, it is considered to be within the scope of the invention that the bellows body member 12 have any type of overall configuration such as a triangular or square cross-sectional configuration as long as the basic overall operation of the bellows smoking pipe remains substantially as described herein.

The bellows body member 12 is essentially of resilient thin-wall construction and defines a smoke expansion cooling chamber 17 therein. The chamber 17 is selectively variable in volume as the bellows body member 12 is selectively compressed or expanded by the user.

The bellows body member 12 is provided with an access opening 18 in end wall 15 in order that the smoke expansion cooling chamber can be periodically cleaned. Support members 19 and 20 are provided on the bellows body member 12 so as to maintain the bellows smoking pipe II in a horizontally oriented rest position. The support members 19 and 20 also served as handles when the bellows smoking pipe is actually being used.

As shown in FIG. 5, a coil spring member 31 is positioned within the bellows body member l2 so as to extend between the end walls 15 and 16. Thus positioned, the coil spring 31 biases the bellows body member 12 into a normally expanded position.

In the preferred embodiment of the invention, support member is fixedly attached to end wall 16. Support member 19 is provided with a plug closure member 21 which makes snap engagement within the access opening 18 so as to maintain the smoke expansion cooling chamber in a closed airtight condition with no access thereto except through check valve means provided in association therewith as described hereinafter. It is within the scope of the invention that the configuration and location of the support members 19 and 20, access opening 18 and plug closure member 21 can be selectively varied as to their relative positions with respect to the bellows body member 12 as long as the operation of the bellows smoking pipe remains as described herein.

As shown generally in the drawings and more specifically in FIG. 6, smoke inlet check valve means 22 and smoke outlet check valve means 23 are positioned through the wall of the bellows body member 12 and are in open communication of the smoke expansing cooling chamber 17 defined by the bellows body member 12.

The smoke inlet check valve means 22 consists of a valve body 24 having a smoke inlet one-way check valve 25 positioned therein. The one-way smoke inlet check valve 25 permits smoke to enter the smoke expansion cooling chamber 17 during the expansion of the bellows body member 12 but closes when the bellows body member is compressed or contracted.

The smoke outlet check valve means 23 is provided with a valve body 26 having a smoke outlet one-way check valve 27 positioned therein. The one-way smoke outlet check valve 27 permits smoke to leave the smoke expansion cooling chamber 17 during compression or contraction of the bellows body member 12, but the smoke outlet valve 27 remains closed during the expansion of the bellows body member 12.

The smoke generating bowl member 13 is positioned on the smoke inlet check valve body 24 which extends outwardly from the bellows body member 12. The bowl member 13 is provided with a smoke bore 28 there through which is in open communication with the smoke inlet one-way check valve 25.

The smoke generating bowl member 13 can be of any suitable material such as soapstone and defines a tobacco receiving and burning bowl chamber 29 in the upper portion thereof. The lower portion of the smoke generating bowl member 13 is provided with cooling fins or convolutions 30.

The tubular stem mouth member 14 consists of a flexible tube which is mounted on the valve body 26 and is in open communication therewith so as to receive cooled smoke from the smoke expansion cooling chamber 17 through the smoke outlet check valve 27. The mouth member 14 can be of any configuration or length as long as it directs cooled smoke towards or into the mouth of the user. Further, the mouth member can have any desired configuration such as a standard smoking bit or mouthpiece.

In operation, the substance to be smoked is introduced in the chamber 29 and is ignited. The flexible bellows body member 12 is initially compressed or contracted to a partially collapsed position. The bellows body member 12 is then permitted to expand so as to draw smoke from the smoke generating bowl 13 through the smoke inlet one-way check valve 25 into the expanding smoke cooling expansion chamber 17. When the smoke has cooled as desired by the user, the user then selectively compresses or contracts the bellows body member 12 so as to drive the cooled smoke from the contracting cooling chamber 17 through the smoke outlet one-way check valve 27 into the tubular stem mouth member 14. Subsequently the cooled smoke is directed through the mouth member 14 into the mouth of the user as desired.

It is thus seen that a unitary, inexpensive bellows smoking pipe is provided which has smoke cooling capabilities hitherto not found in the prior art smoking devices.

Various modifications of the invention may be made without departing from the principle thereof. Each of these modifications is to be considered as included in the hereinafter appended claims unless these claims, by their language expressly provide otherwise.
